Your 7 Steps to ICO.

I. Legal.

- Define the jurisdiction for your incorporation (however, ICO may be conducted without that, as in a case of DAO);

Here's a link to a table containing info on legality of Bitcoin by country or territory (bitcoin is a virtual currency or a token, therefore all other tokens are treated similarly to bitcoin):

- Develop Token Model (Economy) which wouldn't meet the requirements of Howey Test (The US Supreme Court case of SEC v Howey established the test for whether an arrangement involves a security):

1. An investment of money;
2. in a common enterprise;
3. with an expectation of profits predominantly from the efforts of others.

Here's the link to a legal paper explaining this issue in great details: https://www.coinbase.com/legal/securities-law-framework.pdf

V. Mitigate Risks.

2. To not allow any individual, founder, investor, or developer on a project having a full control of funds: we should hold funds in multi-signature wallets and employ escrow partners to hold the keys to the wallet.

VI. Raise Capital Structure.

There are multiple questions we have to address, including:

- What is the ratio between the supply of token offered to market at sale time and the supply preallocated to you?

- How do we create a token distribution that is most advantageous for you?
